Windows 10: Cannot sign into Yahoo Mail Web after KB5017380 and KB5017500 updates

Hi, I have uninstalled updates KB5017380 and KB5017500 manually and Yahoo mail's web version is working again. However, Windows has reinstalled them both automatically. Should I disable these updates?

:)

 

"Stay signed in" for Yahoo Mail doesn't work.

The "Stay signed in" box is ticked but I have to enter my email address and password manually or call upon Roboform to do it.
In the latter case, it's a two step process. It first enters my email address and I then have to tell it to put my password in (fill boxes etc).

Most frustrating.

What do I need to do so that Yahoo Mail obeys "Stay signed in" ?

 

Mail APP insecure according to Yahoo


I was setting up my Yahoo account in the Windows Mail App. I received this from Yahoo:

 

YAHOO MAIL and email apps

Hi clayto

Yahoo has been going through some changes as Verizon lays its hands around the product. You get messages if you try to access the web view on the old IE with a desire to push you to a new browser.

I recognize you are using app I only mention as it relates to things happening at Yahoo.

Any chance you have two step verification on for Yahoo in which case you need an app password to access.

Just for my clarification, you are trying to access your Yahoo mail account through your Windows 10 mail app, correct?

You might also see if any Credentials are being stored in the Windows Credential Manager for Yahoo. (Click start, type Credential Manager)
